"I had three different people groups in who came in and gave me an estimate and what might be needed and what they discovered is that for some reason when the house was built 16 years ago, they did not really do adequate insulation.  I did feel very comfortable with Precise & Snug.  They were good about being able to show me pictures.  They showed how it looks up on the attic.  When you are in the process, the told us that they can do this and that and it would cost so much and the final bill was $20,000.  I would not use their service in the future."

"Butch was prompt on coming to our home and getting us an estimate before he left. They arrived on time, got their work done and did a nice job of cleaning up. It's too early to grade how the new insulation is doing as far as comfort and energy efficiency."

Insulation questions, answered by experts

Most homeowners installing blown-in insulation as a one-off DIY project should simply rent a blower. They tend to be very heavy, and contractor-grade machines can cost $13,000 to $16,000.

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.

Water freezes at 32 degrees Fahrenheit, but the actual temperature that can cause frozen pipes can vary. Generally, it takes 12 hours for pipes to freeze at 32 degrees Fahrenheit.

Uninsulated pipes can freeze if it’s 20 degrees Fahrenheit or colder for over three hours. If your pipes are insulated, it can take six hours or longer for pipes to freeze. Note that some pipe types freeze more often than PEX pipes. Copper pipes freeze more often because the copper conducts energy and loses heat quickly.

Reflective and high R-value batt or roll insulation are often considered energy-efficient, offering significant thermal resistance benefits.

Vapor barriers in attics are a bit outdated and most areas no longer recommend them for attic spaces. For vented attics, the best method is usually to install drywall and cover it with latex paint before attaching insulation fiberglass, cellulose, or foam insulation. When renovating an attic to use as a living space, a contractor can guide you on the best way to cover insulation.
